Selena Gomez takes a breather backstage before rehearsals for the 2013 MTV Movie Awards on Friday afternoon in Burbank, California.

“This performance will be the first time I will be singing in a head piece. I’ve been getting used to that,” Selena shared with MTV.

Selena added, “It’s the first time I’ll be singing and dancing at the same time. I’ve done it on tour a little bit, but I’ve never done a full song that’s choreographed, so that’s going to be really interesting for me to do, and hopefully I’ll do a good job because I’m nervous.”
